PROCESS FOR OBTAINING CERIC OXIDE AND CERIC OXIDE WITH NEW MORPHOLOGICAL CHARACTERISTICS

摘要

The present invention relates to a process for obtaining a ceric oxide. More specifically, the invention relates to a process for increasing and stabilizing at high temperature the specific surface of a ceric oxide. /P P The process of the invention which consists in preparing a ceric oxide by calcination of a ceric hydroxide is characterized by the fact that the ceric hydroxide is subjected to a solvothermal treatment, before the calcination operation /P P The invention also relates, as new industrial products, to ceric oxide with new morphological characteristics.
